The other day I finally got around to taking a backup of an ancient Nexus 7. A Stack Exchange answer by camalot lists a few methods for turning it into plain files, so I go ahead and try the one that doesn’t require me to download anything…
% { printf "\x1f\x8b\x08\x00\x00\x00\x00\x00"; tail -c +25 ../clipper2.adb; } | tar -xvz
...
gzip: stdin: unexpected end of file
tar: Child returned status 1
tar: Error is not recoverable: exiting now
Uh-oh.
